CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 454,045, dated June 16,1891.

Application filedIebrnary 26, 1891. erial No. 382,917. (No model.)

To all whom it may concern:

Be it known that I, DORA HIRSH, a citizen of the United States, residingin Lancaster, in the county of Lancaster and State of Pennsylvania, haveinvented certain Improvements in Oar-Couplings, ofwhich the following isa specification.

This invention relates to improvements in automatic car-couplers; andthe invention consists in the construction and combination of theseveral parts, as hereinafter fully described, and specifically pointedout inthe claims.

In the accompanying drawings, which form a part of this specification,Figure l is a side View of one of my couplers, shown detached from thecar and having both the draw-bars engaged therewith, and Fig. 2 avertical longitudinal section of the same. Fig. 3 is a verticallongitudinal section of a modified form of the coupler. Fig. 4 is a topor plan view of the ends of two cars connected by the coupler. Fig. 5 isan enlarged view of the lever for uncoupling the cars. Fig. 6 is an endView of the draw-head shown in Figs. 1, 2, and 4, the draw-head beingconnected therewith; and Fig. 7, an end view of the modified form ofdraw-head shown in Fig. 3, the draw-bar being detached.

Similar letters indicate like parts throughout the several views.

Referring to the details of the drawings, A A indicate hollowdraw-heads, which may be either circular or rectangular incross-section, as shown, respectively, in Figs. 0 and '7.

The draw-heads illustrated in the drawings are divided internally intotwo sections by transverse partitions a and have openings a in theirends. The partitions prevent the draw-bars from being driven too farinto the head, and at the same time form a bearing for the draw-bar inbacking the train.

The cylindrical draw-head A (shown in Figs. 1 and 2) has a longitudinalslot to cut in the top of both sections thereof, the metal closing theouter ends of which forms a bearing g, that is engaged by the drawbar,as will be explained. The bearing g is carried down somewhat, so that itcloses the upper part of the end of the cylinder, thus increasing thebearing-surface.

In Fig. 3 is shown a modification in the construction of the draw-head,in which the slot is omitted and the bearing formed by a lip h coveringthe upper part of the end opening a 5 5 The slot may also be omitted inthe cylindrical form of the draw-head, or the rectangular form may bemade with the slot, as is most desirable.

B indicates draw-bars constructed of spring metal, the outer ends I) ofwhich are bent back over the main portions and constitute spring. bars,which make vertical angles therewith. The vibrating ends of thespring-bars are bent downward and then again upward, so as to formshoulders I), which engage the bearings g or it and loops 12 thatembrace said bearings, as seen in Figs. 2 and 8. lVith the slotteddraw-heads th e shoulders of the springbars pass upward through theslots to, but in the modified construction they rest against the tops ofthe draw-heads. The outer arms of the loops 17 extend upward outside ofand above the ends of the draw-heads and have bosses 1) formed thereon,that serve as a rest for the heads d of the operating-levers D. Theseheads engage the reduced ends of the said arms of the loops, beingretained thereon by nuts and have jaws (Z formed on their ends, betweenwhich the levers are pivoted, as shown in Figs. 5 and 6. Upon the leverD there is constructed a lug d, provided with an elongated slot (1 Fig.6, through which a fulcrum-pin E, fixed in the platform of the car,passes, the lever being held thereon by the enlarged head 6.

In Fig. 4- is shown two cars G connected by a cylindrical draw-headconstructed as just described. This draw-head is detachable from thedraw-bars B of one or both cars; but, if preferable, the d raw-head maybe permanently secured to one of the cars in the same manner as with anyother coupler, and have only one end constructed to be detachablyengaged .by a draw-bar.

To couple the cars, the draw-head being connected with. one, thedraw-bar to be e11- gaged therewith is guided by its lever D, having theend elevated or depressed by the vertical movement of said lever and ahorizontal movement communicated thereto by a longitudinal movement ofthe lever on the fulcrum-pin E.

To uncouple the draw-bar, the end thereof is depressed, as shown by thebroken lines F, Fig. 3, by a vertical movement of the lever D, (shown bydotted lines f, Fig. 6,) so as to disengage the shoulder b from thebearings g or h.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a car-coupler, the combination, with a hollow draw-head having anopening in the end, of a bearing formed in said open end, a draw-bar,and a spring-actuated shoulder connected with the draw-bar and adaptedto engage the bearing of the draw-head, substantially as and for thepurpose specified.

2. In a car-coupler, the combination, with a hollow draw-head open atthe end and having a slot cut through the wall thereof, of a drawbar anda spring-actuated shoulder connected with the draw-bar and adapted toengage the slot in the draw-head, substantially as and for the purposespecified.

3. In a car-coupler, the combination, with a hollow draw-head having anopening in the end, of a bearing formed at said opening, a draw-barhaving the end bent back over the body thereof and forming a spring-bar,and a shoulder formed 011 the spring-bar adapted to engage the bearingof the draw-head, substantially as and for the purpose specified.

4. In a car-coupler, the combination, with a hollow draw-head having anopening in the end, of a bearing formed at said opening, a draw-bar, aspring-actuated bar connected With the draw-bar and having a shoulderand loop, and a lever connected with the outer arm of said loop,substantially as and for the purpose specified.

5. In a cancoupler, the combination, with a hollow draw-head having anopening in the end, of a bearing formed at said opening, a draw-bar, aspring-actuated bar connected with the draw-bar and having a shoulderand loop, and a lever connected with the outer arm of said loop andhaving an elongated slot, and a pin secured to the car and engaging theelongated slot of the lever, all constructed and operating substantiallyas and for the purpose specified.
